Evil Ruka soon, she's going to throw a massive tantrum when she finds out Kazuya and Chizuru have been getting closer, even when Kazuya finally breaks up with her (instead of trying to force Ruka to break up with him) she'll still throw a massive tantrum and on the otherside Umifags will watch Umi lose his "chad" status when he tries to drive a wedge between Kazuya and Chizuru using underhanded means, if he finds out about Ruka I expect him to try and use this against Kazuya, Mini will simp for Kazuya endlessly so she can help clear up any misunderstandings unless she starts aiming for Kazuya herself, I no longer consider Mami "final boss" material since I actually expect Kazuya to part ways with her positvely, that is to say, Ruka and Umi will be the final bosses.
